The safety of insulin aspart was evaluated in two treat-to-target trials of 6 months duration, conducted in patients with type 1 diabetes or type 2 diabetes [see Clinical Studies (14) ]. The data in Table 1 reflect the exposure of 596 patients with type 1 diabetes to insulin aspart in one clinical trial with a mean exposure duration to insulin aspart of 24 weeks. The mean age was 39 years. Fifty-one percent were male, 94% were Caucasian, 2% were Black and 4% were other races. The mean body mass index (BMI) was 25.6 kg/m 2 . The mean duration of diabetes was 15.7 years and the mean HbA 1c at baseline was 7.9%. The data in Table 2 reflect the exposure of 91 patients with type 2 diabetes to insulin aspart in one clinical trial with a mean exposure duration to insulin aspart of 24 weeks. The mean age was 57 years. Sixty-three percent were male, 76% were Caucasian, 9% were Black and 15% were other races. The mean BMI was 29.7 kg/m 2 . The mean duration of diabetes was 12.7 years and the mean HbA 1c at baseline was 8.1%. Common adverse reactions were defined as events that occurred in ≥5%, excluding hypoglycemia, of the population studied. Common adverse events that occurred at the same rate or greater for insulin aspart-treated patients than in comparator-treated patients during clinical trials in patients with type 1 diabetes mellitus and type 2 diabetes mellitus (other than hypoglycemia) are listed in Table 1 and Table 2, respectively. Table 1: Adverse reactions that occurred in ≥ 5% of Type 1 Diabetes Mellitus Adult Patients treated with insulin aspart and at the same rate or greater on insulin aspart than on comparator Insulin Aspart + NPH (%) (n= 596) Regular Human Insulin + NPH (%) (n= 286) Headache 12 10 Injury accidental 11 10 Nausea 7 5 Diarrhea 5 3 Table 2: Adverse reactions that occurred in ≥ 5% of Type 2 Diabetes Mellitus Adult Patients treated with insulin aspart and at the same rate or greater on insulin aspart than on comparator Insulin Aspart + NPH (%) (n= 91) Human Regular Insulin + NPH (%) (n= 91) Hyporeflexia 11 7 Onychomycosis 10 5 Sensory disturbance 9 7 Urinary tract infection 8 7 Chest pain 5 3 Headache 5 3 Skin disorder 5 2 Abdominal pain 5 1 Sinusitis 5 1 Severe Hypoglycemia Hypoglycemia is the most commonly observed adverse reaction in patients using insulin, including insulin aspart products . The rates of reported hypoglycemia depend on the definition of hypoglycemia used, diabetes type, insulin dose, intensity of glucose control, background therapies, and other intrinsic and extrinsic patient factors. For these reasons, comparing rates of hypoglycemia in clinical trials for insulin aspart with the incidence of hypoglycemia for other products may be misleading and also, may not be representative of hypoglycemia rates that will occur in clinical practice. Severe hypoglycemia was defined as hypoglycemia associated with central nervous system symptoms and requiring the intervention of another person or hospitalization. The incidence of severe hypoglycemia in: Adult and pediatric patients with type 1 diabetes mellitus who received subcutaneous insulin aspart was 17% at 24 weeks and 6% at 24 weeks, respectively [see Clinical Studies (14) ] . Adult patients with type 2 diabetes mellitus who received subcutaneous insulin aspart was 10% at 24 weeks. Adult and pediatric patients with type 1 diabetes mellitus, who received insulin aspart via continuous subcutaneous insulin infusion by external pump was 2% at 16 weeks and 10% at 16 weeks respectively. No severe hypoglycemic episodes were reported in adult patients with type 2 diabetes mellitus receiving insulin aspart via continuous subcutaneous insulin infusion by external pump at 16 weeks. Allergic Reactions Some patients taking insulin, including insulin aspart products have experienced erythema, local edema, and pruritus at the site of injection. These conditions were usually self-limiting. Severe cases of generalized allergy (anaphylaxis) have been reported. Adverse Reactions Associated with Insulin Initiation and Glucose Control Intensification Intensification or rapid improvement in glucose control has been associated with a transitory, reversible ophthalmologic refraction disorder, worsening of diabetic retinopathy, and acute painful peripheral neuropathy. However, long-term glycemic control decreases the risk of diabetic retinopathy and neuropathy. Lipodystrophy Administration of insulin, including insulin aspart products, subcutaneously and via subcutaneous insulin infusion by external pump, has resulted in lipoatrophy (depression in the skin) or lipohypertrophy (enlargement or thickening of tissue) in some patients [see Dosage and Administration (2.2) ]. Peripheral Edema Insulins, including insulin aspart products, may cause sodium retention and edema, particularly if previously poor metabolic control is improved by intensified insulin therapy. Weight Gain Weight gain has occurred with insulins, including insulin aspart products, and has been attributed to the anabolic effects of insulin and the decrease in glucosuria. 6.2 Immunogenicity As with all therapeutic proteins, there is potential for immunogenicity. The detection of antibody formation is highly dependent on the sensitivity and specificity of the assay. Additionally, the observed incidence of antibody (including neutralizing antibody) positivity in an assay may be influenced by several factors including assay methodology, sample handling, timing of sample collection, concomitant medications, and underlying disease. For these reasons, comparison of the incidence of antibodies in the studies described below with the incidence of antibodies in other studies or to other insulin aspart products may be misleading. In a 6-month study with a 6-month extension in adult subjects with type 1 diabetes, 99.8% of patients who received insulin aspart were positive for anti-insulin antibodies (AIA) at least once during the study, including 97.2% that were positive at baseline. A total of 92.1% of patients who received insulin aspart were positive for anti-drug antibodies (ADA) at least once during the study, including 64.6% that were positive at baseline. In a phase 3 type 1 diabetes clinical trial of insulin aspart, initial increase in titers of antibodies to insulin, followed by a decrease to baseline values, was observed in regular human insulin and insulin aspart treatment groups with similar incidences. These antibodies did not cause deterioration in glycemic control or necessitate increases in insulin dose. 6.3 Post Marketing Experience The following adverse reactions have been identified during post-approval use of insulin aspart products. Because these adverse reactions are reported voluntarily from a population of uncertain size, it is generally not possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Medication errors have been reported in which other insulins have been accidentally substituted for insulin aspart products. Localized cutaneous amyloidosis at the injection site has occurred with insulin aspart products. Hyperglycemia has been reported with repeated insulin injections into areas of localized cutaneous amyloidosis; hypoglycemia has been reported with a sudden change to an unaffected injection site.

Pregnancy Risk Summary Available information from published randomized controlled trials with insulin aspart products use during the second trimester of pregnancy have not reported an association with insulin aspart products and major birth defects or adverse maternal or fetal outcomes (see Data ). There are risks to the mother and fetus associated with poorly controlled diabetes in pregnancy (see Clinical Considerations ). In animal reproduction studies, administration of subcutaneous insulin aspart to pregnant rats and rabbits during the period of organogenesis did not cause adverse developmental effects at exposures 8-times and equal to the human subcutaneous dose of 1 unit/kg/day, respectively. Pre- and post-implantation losses and visceral/skeletal abnormalities were seen at higher exposures, which are considered secondary to maternal hypoglycemia. These effects were similar to those observed in rats administered regular human insulin (see Data ). In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively.

The estimated background risk of major birth defects is 6 to 10% in women with pre-gestational diabetes with a periconceptual HbA 1c >7% and has been reported to be as high as 20 to 25% in women with a periconceptual HbA 1c >10%. The estimated background risk of miscarriage for the indicated population is unknown. Clinical Considerations Disease-Associated Maternal and/or Embryo-Fetal Risk Poorly controlled diabetes in pregnancy increases the maternal risk for diabetic ketoacidosis, preeclampsia, spontaneous abortions, preterm delivery, and delivery complications. Poorly controlled diabetes increases the fetal risk for major birth defects, stillbirth, and macrosomia related morbidity.

Data Human Data Published data from 5 randomized controlled trials of 441 pregnant women with diabetes mellitus treated with insulin aspart products during the late 2 nd trimester of pregnancy did not identify an association of insulin aspart products with major birth defects or adverse maternal or fetal outcomes. However, these studies cannot definitely establish the absence of any risk because of methodological limitations, including a variable duration of treatment and small size of the majority of the trials. Animal Data Fertility, embryo-fetal and pre- and postnatal development studies have been performed with insulin aspart and regular human insulin in rats and rabbits.

In a combined fertility and embryo-fetal development study in rats, insulin aspart was administered before mating, during mating, and throughout pregnancy. Further, in a pre- and postnatal development study insulin aspart was given throughout pregnancy and during lactation to rats. In an embryo-fetal development study insulin aspart was given to female rabbits during organogenesis.

The effects of insulin aspart did not differ from those observed with subcutaneous regular human insulin. Insulin aspart, like human insulin, caused pre- and post-implantation losses and visceral/skeletal abnormalities in rats at a dose of 200 units/kg/day (approximately 32 times the human subcutaneous dose of 1 unit/kg/day, based on human exposure equivalents) and in rabbits at a dose of 10 units/kg/day (approximately three times the human subcutaneous dose of 1 unit/kg/day, based on human exposure equivalents). No significant effects were observed in rats at a dose of 50 units/kg/day and in rabbits at a dose of 3 units/kg/day. These doses are approximately 8 times the human subcutaneous dose of 1 unit/kg/day for rats and equal to the human subcutaneous dose of 1 unit/kg/day for rabbits, based on human exposure equivalents.

The effects are considered secondary to maternal hypoglycemia.

Pediatric Use The safety and effectiveness of KIRSTY to improve glycemic control have been established in pediatric patients with diabetes mellitus. Use of KIRSTY for this indication is supported by evidence from an adequate and well-controlled study of insulin aspart in 283 pediatric patients with type 1 diabetes mellitus aged 6 to 18 years and from studies in adults with diabetes mellitus .

• is contraindicated
• During episodes of hypoglycemia [see Warnings and Precautions (5.3) ]
• In patients with hypersensitivity to insulin aspart products or any of the excipients in KIRSTY [see Warnings and Precautions (5.5) ]
• During episodes of hypoglycemia ( 4 ).
• Hypersensitivity to insulin aspart products or any of the excipients in KIRSTY.

Excess insulin administration may cause hypoglycemia and hypokalemia . Mild episodes of hypoglycemia usually can be treated with oral glucose. Adjustments in drug dosage, meal patterns, or exercise may be needed. More severe episodes with coma, seizure, or neurologic impairment may be treated with intramuscular/subcutaneous glucagon or concentrated intravenous glucose.

Sustained carbohydrate intake and observation may be necessary because hypoglycemia may recur after apparent clinical recovery. Hypokalemia must be corrected appropriately.
